Siemens Features Powered Up Building Energy Efficiency Solutions at Light+Building 2014

Situated in Hall 11 of Light+Building 2014, the main theme of Siemens booth was “Power up your building efficiency.” The company displayed different building energy management systems at the lighting show that runs from March 31-April 4 in Frankfurt Fair and Exhibition Center in Germany.

The building energy management systems are capable of collecting various information to build a carbon emission trade platform. The company’s Desigo CC building management system for instance covers heating, ventilation, air conditioning, lighting, shading, room automation and power, as well as security functions such as video surveillance and intrusion detection. The system is an open platform that supports standard protocols including BACnet, OPC and other IT standards and can be integrated into third-party products.

The German company also showcased its streetlight control system. With the installation of a control system into every streetlight, all city streetlights can be monitored. Streetlights can be designed to switch on or off during peak or off-peak hours, and brightness can be adjusted to reduce energy consumption. Light sensors can even be added into the lamps to detect environmental changes, such as increasing brightness on a foggy or cloudy day to protect pedestrian safety.

In addition, the system can streamline data simultaneously onto handheld devices, such as a tablet or mobile phone. The updated data will help construction workers make adjustments in accordance to real-life situations.

Besides being applied to LED streetlights, the same control system can be used in conventional light sources. This can lower costs for clients, and some government agencies are already using this system, such as the Dusseldof government in Germany. However, this smart streetlight system does not come cheap. A single streetlight control system costs more than EUR 1,500 (US$ 2,066.25), and every city has more than 10,000 streetlights. Installation costs can also be rather costly, so clients must evaluate whether installation costs can be paid off with energy conserved, said LEDinside Research Director Roger Chu.
